Mathematicus by Cesare Baj is a board game that stands out for its strong educational mission and its ability to make mathematics accessible and enjoyable for a wide age range, from 8 to 99 years old. Created by science popularizer Cesare Baj, in collaboration with Bocconi University and the University of Milan, this game aims to debunk the idea that mathematics is dry and difficult. The game unfolds on a board, but its complexity comes from the richness of its materials: 416 cards with 1600 questions across four different levels, a detailed instruction manual, and a 176-page book full of mathematical curiosities. Additionally, it includes analog calculation tools like the slide rule and tiles for composing numbers in ancient numbering systems (Babylonian, Egyptian, Mayan) and in the binary system. Mathematicus doesn't require advanced mathematical knowledge; instead, it focuses on promoting the understanding of ancient and "exotic" mathematics, demonstrating the universality of this discipline. The game's dynamic, which resembles "Snakes and Ladders" with pawns moving forward (or backward) on squares, is enriched by multiple variables that make the outcome always unpredictable. The objective is to compete by answering captivating questions, using historical calculation tools, and tackling challenges that lead to deep satisfaction. The game is modular, offering different modes (basic, normal, advanced) that allow for a personalized learning experience, making it a true educational tool also adopted by schools.
